Abstract: For effecting cryptographic communications between entities I, j using a common cryptokey, each or the entities I, j generates a common cryptokey by applying an identifier transformation algorithm and a secret private key, which have previously been distributed from a center, to the identifier of the other entity with which to communicate (step 3). In a transmitting side, one-time pass cryptographic communication random number data are generated and encrypted by the common cryptokey, a plaintext is encrypted using the random number data, and the encrypted random number data and the encrypted plaintext are combined into an encrypted communication text (step 4). In a receiving side, the encrypted random number data in the encrypted communication text are decrypted using the common cryptokey, and the encrypted plaintext is decrypted using the decrypted random number data as a key (step 5).

Title: Hologram diffusion component
Inventor: JAU WEI-JUNG
IPC: H01L21/00
Filed: 1997-08-11
Granted: 2000-05-01
Abstract: A conventional diffusion device not only alters the phase of light but also the amplitude factor thereof. As a result, the utilization efficiency of the light passed through the diffusion device is decreased without achieving the effect of uniformly blending colors of different wave sources. The present invention uses the Fraunhofer diffraction principle and an iterative computer programming technique to design a hologram diffusion device that can achieve the effect of uniformly blending colors of different wave sources. Since the diffusion device according to the present invention changes only the phase of light without altering the light intensity, the light transmittance can be greatly increased.

Granted: 2000-10-01
Abstract: In a free form machining tool 10 for machining a surface to be machined while bringing the lower end into contact with the surface to be machined by a rotation around an axis z, the tool comprises a spherical tool 12 having a spherical surface machining section 13 on the lower portion, and a bearing 14 for supporting the spherical tool by an axis a of rotation which passes through the center O of the spherical surface and is different from the axis. The tool also includes rotating means 16 (for example, a turbine) for rotating the spherical tool around the axis of rotation. Thus, even if the spherical surface machining section comes into contact with the surface to be machined on the axis (radius: 0) of the tool, the spherical surface machining section is rotated around the axis a of rotation which is different from the axis z. Therefore, a peripheral speed of the axis is not zero (0). It is possible to efficiently work a freely curved surface with high accuracy and high quality by the use of a conventional three-axial NC machining apparatus.

Inventor: BENNETT KEVIN W
IPC: G02B6/293
Filed: 1998-04-14
Granted: 1999-09-11
Abstract: The variables and parameters previously understood to effect the gain spectrum of an optical amplifier 13 were: (1) the wavelengths to be amplified; (2) the input power levels at those wavelengths; (3) the characteristics of the amplifying medium 30; (4) the insertion loss spectra of the amplifier's components, including any filter(s) used for gain flattening; (5) the pump band chosen to pump the amplifying medium 20; (6) the total amount of pump power supplied in the chosen pump band. An additional fundamental variable has been identified which can be used to control the gain spectrum of an optical amplifier 13, namely, the center wavelength of the spectrum of the pump's output power within the chosen pump band. Methods and apparatus for using this variable for this purpose are disclosed. For example, a transmission system is disclosed having a transmitter 11 and a receiver 10 connected by an optical fiber 12. A plurality of optical amplifier 13 are located along the optical fiber 12 to amplify signal channels between the transmitter and receiver. Each of the amplifiers has a pump light source 21, the wavelength of which is such that contributions to differential gain due to pump light wavelength related effects is substantially reduced. Also disclosed is a WDM transmission system having a transmission path including a concatenation of laser diode pumped optical amplifiers 13 wherein the gain spectrum of an amplifier is controlled at least in part by a feedback loop regulating the temperature of its laser diode pump 21. The feedback loop may for instance derive current applied to the pump, of the emission wavelength of the pump, or of the disparity between the power output from the amplifier in one of the multiplexed signal channels and that from at least one another of the channels.
